Abstract

Metasurfaces provide a great flexibility in light management through interaction with nanostructured surface. Although successful in demonstrating fantastic optical functionalities, metasurfaces still suffer from high optical losses which highly constraint on enhancing their optical performance. In this talk, I will present a design method to realize a plasmonic metasurface with a circular polarization conversion efficiency higher than 50% in transmission at near-infrared wavelengths. We further demonstrate several metasurface-based components such as beam deflector and flat focusing lens with record operating efficiency based on the proposed metasurface.
